State police say initial reports from first responders indicated the single passenger plane was fully engulfed by flames and because of the crash location, posed a risk to traffic safety.

Police say one northbound lane has been reopened to traffic and the right-hand lane is expected to remain closed for some time.

Northbound traffic was redirected at Exit 21 in Swanton and through the Canadian border while emergency crews worked to extinguish the plane and provide medical attention.

Members of the Vermont State Police Bureau of Investigation and Vermont Agency of Transportation are investigating. The Federal Aviation Administration has been notified and will conduct a further investigation.
